AERlAL. TOP- Specification of Letters Patent.

Patented Feb. 27,1905.

Application filed June 20, 1905. Serial No. 266,131;

To all whom it may concern."

'Be it-known that- I, ALBERT L. PLA'rr, a citizen of the United Statesof America, residing at Clinton, in the county of Dewitt and State ofIllinois, have invented certain new and use- "embo yingmeans forvimparting a rapid spinning motion to the whirlingmember y a singlespiral Wrap of thecord about the spinnin -'stem of said member. 3

V%'ith these and other objects in view, which will more readily appearas the nature I of the invention, is better understood, the

same consists in the novel construction,.com-

bination, and arrangement of parts, which will be hereinafter more fullyillustrated, described, and claimed.

The essential feature of the invention involved in the manner of housinand guiding the operating-cord'is necessari y susceptible to somestructural change withoutdeparting from the sec e of the invention; buta preferred embodiment thereof is shown in the accompanying drawings, inwhich Figure 1 1s a perspective view of a top em-" bodying the presentinvention, showing the whirling member carried by the su portinghandle111 a osition to be'operat eci. Fig. 2 isv a longitudinal sectional viewof the top, showing the arrangement of theoperatingcord for spinning androjec'ting the whirling member. Fig. 3 is a etail view of the whirlingmember as it appears while in flight.

Like reference-numerals designate correplponding parts in the severalfigures of therawmgs.

' The toy in its general organization essentially comprises a sup ortingmember 1, a whirling member 2, an an operating-cord 3. The supportingmemberof thetoy is preferably in'the' form of a tubular handle providinga holder which can be conveniently and readily grasped by one hand ofthe operator,

thus leaving the other hand free for manipulating the cord to providefor whirling and projecting the whirling member or top proper: he longtudinal-bore 4 of the said supporttially straight line.

ing handle extends throughout the entire length of the latter andconstitutes a guiding means for the spinning-stem 5 of the whirlinmember, 2, whereby the latter is pro'ecte fromc-the supporting handle ina su stan- The said whirling memher 2 essentially consists of the sinning-stem 5 and the screw-propeller bla e 6, secured fast upon one endof the stem and disposed at right angles to the axis thereof. "lhe propeller-bladc 6 is formed with the opposite reversely-inclined Wings 7,which provide the conventional screw-propeller action when a whirlingmotion is imparted to the whirling member or top pro er and which actionserves to maintain tie whirling member in flight as long as the speed ofrotation is sufficient.

A distinctive feature of the'invention resides in the novel manner ofhousin and guid ing the operating-cord 3. This cord is threaded througha cord-holding guide-eye 8, piercing the wall of the tubular handle 1near the upper end. of the latter, and'is designed to be drawn or pulledthrough a di'awing-kerf 9,

formed in the top edge of the handle in a hi her plane than the eye 8.The said kerf 9 IS Iormed with a downwardly-sloping base 10 to. form aguiding-surface over w oh the o crating-cord may be freely drawn,,and int e interval between the guide-eye .8 and the kerf 9 the cord 3 isdesigned to be given a single s iral twist 3 about the stem 2 of the'whir mg member. By reason of this single spiral twist of theoperating-cord the latter may be quickly drawn-from the eye 8 throughthekerf 9 to im parta rapid-spinning motion to the stem-2 and the propellercarried thereby, whileat the same time serving to mechanically lift thestem 5 out ofits guidingbore 4 and forcibly project the whirling memheror top proper into the air;

, Inoperating the toy it is simply necessary to drop the stem 5 in thesup orting-handle, place a single twist of the cor about the said stem,and drop the pull end thereof into the kerf 9. It isthen simplynecessary to draw. out the cord rapidly through the kerf to secure theaction referred to.

To provide proper and. free play for the spiralwrap of theoperating-cord, the su porting-handle 1 is formed in its upper en withan enlarged housing-socket 11, which is an enlargement of the guidin-bore. w

I Having thus desc 'bed t e invention, what is claimed, and desired tobe secured by Letters Patent, is

An aerial top, com rising a tubular supporting-handle provid ed near itsupper end with a transversely-disposed cord-holding guide-eye, and inits top edge in a hi her plane than the eye with a downwardly-s 0pingdrawing-kerf, said handle being also pro- Vided at its top edge with anenlarged housing-socket, a whirling member consistin of a spinning-stemlying within the bore 0? the supporting-handle, and a propeller-bladecar ried by said stem, and an operating-cord assing through theguide-oye and drewinglierf and having its portion between these elementsarranged about said stein in a single spiral wrap, the latter lieingg;arranged to operate in said h0using-socket.

In testimony whereof I aflix my signature in presence of two witnesses.
